Soumen at the site http://en.wikipedia.org/wiki/Meripilus_giganteus it is said that the basidiocarps consist of numerous rosette-like flattened fan-shaped pilei; they are typically 30–80 centimetres (12–31 in) in diameter and 20–30 centimetres (7.9–12 in) high. The individual caps, up to 25 centimetres (9.8 in) diameter and 1–2 centimetres (0.39–0.79 in) thick, arise from a common basal stem.
